The user may not be aware they have this tracking technology on their phone. The toolkit may be some app developer integrating a 3rd party library for analytics.
In fact, I was going to mention an app, Exodus, that can reveal these trackers and in scanning my phone, I found 2!. The first is home assistant, which is understandable, but the second is a Health app my doctor office uses! Man, that irks me!
